I agree with zambi, exfoliation is great, no buts about that. Zambi gave an excellent description: exfoliation gets rid of dead skin cells which sits on the top of skin. Removing this layer of dead skin reveals the newer layers of skin below = smoother and more radiant skin.
For example, picture a copper bracelet. Assuming that we are exposing it to air everyday, the piece of copper will lose its shininess and develop a layer of grey/black tarnish. This layer can be removed, revealing the shiny metal beneath. After a while, this layer will redevelop and you'll need to remove it again if you want the piece of copper to be shiny. Similarly, if you stop exfoliating the skin then the layer of dead cells will rebuild up = rougher skin.
Now to answer the question, scrubs are bad for skin because most scrubs contain broken pieces of nuts or shells (which have hard, sharp rough edges) to rub off the layer of dead skin. The reason why most people get spots in places they are break out free after using a scrub is because the skin is very delicate. When you use a scrub, those sharp edges of the nuts / shells in the scrub tear away at the skin, causing microscopic cuts on the surface of the skin. This means you're irritating the skin, and irritation = break outs. No matter how gently you do it or how gentle the scrub claims the nuts / shells doing the scrubbing are, you will still be irritating the skin which will lead to breakouts.
Never use a scrub, use a chemical exfoliant which instead of using nuts / shell pieces to do the exfoliating, chemical exfoliants uses chemicals which is absorbed into the skin and breaks down the dead skin cells and whatnot. Beta Hydroxy Acids and Alpha Hydroxy Acids is what you're looking for if you're considering exfoliation.
what you're saying is true, i've read so much about all of this. but acids can also damage the skin by making it weaker. i try to limit my use of them plus i've tried many and they all make me break out. it's weird but the acnetix with it's walnut shell actually seems to calm my skin. one of the things i suffered with was small red irritation bumps around my month and chin. i think it was from the sa in the olay cloths that i use. now that i've added the acnetix they're gone. i don't get it myself. i'm sure it's the tea tree oil or the aloe that's calming my skin but i keep expecting break outs because of everything i've read about walnut shells.
my question to you is- shouldn't i have seen break outs by now? i started using the acnetix the first week of july. am i damaging my pores? if i was going to have a bad reaction shouldn't i have had it by now? i was thinking about making an appointment with my esthetician, so she could have a look at my skin to see if i'm damaging the pores.
it's so ironic that i finally find something that works and it's shrouded in all this bad press and contrary research.
